gSocketSetKeepalive: gSocketSetKeepalive

Description Usage Arguments Details Author(s)

View source: R/gioFuncs.R

Description

Sets or unsets the SO_KEEPALIVE flag on the underlying socket. When this flag is set on a socket, the system will attempt to verify that the remote socket endpoint is still present if a sufficiently long period of time passes with no data being exchanged. If the system is unable to verify the presence of the remote endpoint, it will automatically close the connection.

Usage

gSocketSetKeepalive(object, keepalive)

Arguments

object

a GSocket.

keepalive

Value for the keepalive flag

Details

This option is only functional on certain kinds of sockets. (Notably, G_SOCKET_PROTOCOL_TCP sockets.)

The exact time between pings is system- and protocol-dependent, but will normally be at least two hours. Most commonly, you would set this flag on a server socket if you want to allow clients to remain idle for long periods of time, but also want to ensure that connections are eventually garbage-collected if clients crash or become unreachable. Since 2.22
